Producers of Charlie Sheen’s upcoming sitcom, “Anger Management,” blatantly ripped off the project from a former creative partner, according to allegation in a Los Angeles lawsuit.

Jason Shuman and his Blue Star Entertainment group claim they were hired by defendant Joe Roth and his Revolution Studios to develop the “Anger” movie into a small-screen show.

“Shuman spent over a year and a half developing the show’s characters, meeting with Hollywood agents and cable syndication giants, hiring and meeting with actors, writers and show-runners, and pitching ‘Anger Management’ through a progressive syndication structure,” according to the Shuman’s lawsuit.

The plaintiff said he spent two years working on “Anger,” with an eye toward making it a 100-episode hit — a key mark for future syndication profits.

Schuman claims he also helped Revolution make a TBS sitcom based on “Are We There Yet” and proposed a TV version of the movie “White Chicks.”

Sheen, the former “Two And a Half Men” bad boy, is the marquee star of the TV-version of “Anger,” which premieres on FX on June 28.

Roth denied all of Shuman’s claims, and said: “We haven’t received the complaint. I’m familiar with the situation and it is completely without merit.”
